You cannot run any aftermarket mid-section in California legally unless it is C.A.R.B. approved.

Malek I took your advise on another thread and picked up a set of RS Tecknic spacers 18/15... im not lowered so will I still be able to run 255/275 tires when I'm due up for a new set? Don't want to rub but I def do want slightly larger rubber.
